Stereo slide mount and stereo camera

Abstract

A stereo slide mount capable of correctly adjusting the pitch between the films. Horizontal guide grooves 14 R and 14 L are formed on the lower side of the right and left windows of a base frame 11 of the stereo slide mount, and film holder bars 15 R and 15 L are fitted into the guide grooves. Verniers are graduated on the right and left film holder bars under the right window and the left window of the base frame. Cam shafts are turned by being inserted in the bearing holes 18 formed at the ends on the inner sides of the guide grooves, whereby the film holder bars are slid outward to correctly adjust the offset amounts relying on the verniers. After the adjustment, perforations at both ends of the films are engaged with the bosses 16 of the film holder bars so as to be placed in position, and a cover frame 1 is mounted on the base frame 11.

I claim:  
     
       1. A stereo slide mount comprising a base frame and a cover frame, each having a pair of windows with lateral widths for viewing films with perforations having pictures thereon, wherein the lateral widths of the pair of windows are set to be narrower than lateral widths of the pictures of the films, horizontal guide grooves are formed over or under each of the pair of windows of the base frame, film holder bars having bosses formed thereon for engagement with the perforations of the films, are fitted into each of the guide groves in a manner that a gap between the film holder bars can be adjusted, and the film holder bars and the base frame are provided with graduates of different pitches thereby to constitute verniers, so that offset amounts of the film holder bars in a right-and-left direction can be read relying on the verniers. 
     
     
       2. A stereo slide mount according to claim  1 , wherein bearing holes are formed at positions opposed side surfaces of the film holder bars of said base frame, and cam shafts are turned by being inserted in said shaft holes in order to push and slide the film holder bares of which the guide grooves are engaged with cams. 
     
     
       3.
